Abstract: Provided is a method of suppressing burrs that occur during injection-molding of a polyarylene sulfide resin composition, including: adding at least 0.01 to 5 parts by mass of a carbon nanostructure to 100 parts by mass of a polyarylene sulfide resin and melt-kneading at least the carbon nanostructure and the polyarylene sulfide resin.
